Title: Drill bit
Inventor: SHOJI MASAHARU
IPC: E21B10/58
Filed: 1994-02-23
Abstract: PURPOSE:To prevent a drill bit from coming off due to abrasion and to enhance the drilling speed by securing a bit body protecting and cutting plate having several saw-tooth like blades formed therearound together with a tip which is inserted in the front end face of a bit body. CONSTITUTION:Several saw-tooth-like blades 41 are formed around a bit protecting and drilling plate 4, and is secured together with a tip 2 which is inserted in the front end face of a truncated conical part 13 of a bit body 1. Accordingly, the drilling speed is increased, and the drilling is effectively carried out. Further, wing pieces B1, B2, B3, B4 are inclined at an angle of 5 to 8 deg. with respect to the axis 0-0 of the truncated conical part 13. As a result, a pressing force which is exerted, perpendicular to the axial direction during drilling can be decreased so that a drill bit can be attached to the bit mounting bearing with substantially no play. Thereby it is possible to effectively avoid lowering the drilling efficiency at an earlier time.

Title: Engine control apparatus equipped with abnormality detecting function
Inventor: FURUMURA HIROSHI
IPC: G01M15/00
Filed: 1987-03-07
Abstract: PURPOSE:To enhance the reliability of an abnormality detecting function, by using the number-of-rotation signal obtained by analogue processing and the number-of-rotation signal obtained by digital processing and judging abnormality when both signals do not coincide with each other. CONSTITUTION:CPU 14 reads the set value (c) due to an acceleration setting device 6 as a digital signal through an A/D converter 17 to calculate the set number of rotations. Subsequently, when the signal (d) of a comparator 5 outputted when the output of a rotation sensor composed of an electromagnetic pickup 3 exceeds the set value (c) is inputted to an I/O port 3, a result is stored in RAM 16. Next, the number of rotations of an engine is calculated from the number of the pulses of a signal (e) from a waveform shaping circuit 11 converting the AC voltage signal (a) of the pickup 3. CPU 14 outputs a system abnormal signal E2 when an acceleration alarm signal E1 is outputted even though the number of rotations of the engine is smaller than the set number of rotations, and when the signal E1 is outputted even though the number of rotations of the engine is larger than the set number of rotations. By this method, the abnormality of the number of rotations is more certainly detected.
